Printing problem

Please verify that all your clients have the same setup in QuickBooks. For reference the settings are: Select FILE / PRINTER SETUP Within the Printer Setup window, select Check / Paycheck in the Form Field at the top. The Printer Setup window will appear with three tabs: Settings, Fonts, and Partial Page. In the Settings tab Printer Name "PrintBoss 50" Check Style Voucher "Print Company Name and Address" Checked In the Fonts tab Click on the "Font" button. Select Arial 10 Point, Regular. Click on the "Address Font" button. Select Arial 12 Point, Regular. Select EDIT / PREFERENCES Choose the Checking selection on the left hand side of the Preferences window.Under the Company Preferences tab, check the box next to "Print Account Names on Vouchers”.

I have several clients using Printboss to print payroll cheques. One client works okay, but the other prints a cheque that is not the one assigned to that bank and the cheque is not added to the work files although it is for the other company. How can I correct this?Thanks
